Baryon Acoustic Oscillations in tomographic Angular Density and Redshift Fluctuations
Paula S. Ferreira, Carlos Hernández-Monteagudo, Ribamar R. R. Reis
In this work we examine the baryon acoustic oscillations (BAO) in 2D angular and redshift space , with denoting the redshift difference between two given angular sh…
Influence of photometric galaxies redshift distribution in BAO estimation
Paula S. Ferreira, Ribamar R. R. Reis
In the present study, we use the DES Y3 catalog of LRG to incorporate the realistic galaxies' redshift Probability Distribution Function(PDF) into the correlation function cosmolog…
Pz Cats: Photometric redshift catalogs based on DES Y3 BAO sample
Paula S. Ferreira, Ribamar R. R. Reis
Over the years, photometric redshift estimation (photo-z) has advanced through various methods. This study evaluates four distinct photo-z estimators-ANNz2, BPZ, ENF, and DNF-using…
Baryon Acoustic Oscillations from galaxy surveys
Paula S. Ferreira, Ribamar R. R. Reis
We conducted a review of the fundamental aspects of describing and detecting the Baryon Acoustic Oscillation (BAO) feature in galaxy surveys, emphasizing the optimal tools for cons…
